There is no hint or anything about what is the barrier of mana B used, however, there is one interesting aspect, it isn't the aksara or the chanting, but the rune. When both of them reached the climax of the spell or the last phrase of their chanting, the ball of lights around them and their energy came together into the rune. The rune glowed brightly, as all of this fused and was released with more energy. Yet the concern is the last barrier. Lilith cast it without any rune, just ꦏꦸꦭꦲꦩꦤ꧀ꦱꦏꦫꦺꦴꦁꦱ꧉꧉꧉ which means we are safe from harm, but the word isn't 'we' but 'I', sometimes this language pronoun we with I pronoun. Varania needs a rune to appear, and Lilith can just cast it without any rune. Is it connected with the difference between the creature's mana and the spell? I know Lilith has more mana than Varania, it can be a key that Lilith can cast the barrier without any rune because of her higher mana capacity compared to Varania. It means the mana capacity percentage towards the spell is joining the play; when a creature has a little mana or mana A, it relies heavily on mana B or environmental mana.

She snapped her finger *snap* bringing me back to reality. I quickly snapped out of my thinking as Lilith's piercing eyes met mine, and she chuckled, "Thou very doth love to get lost 'i thy thoughts or just musing around, do not thou? (You really do love to get lost in your thoughts or just musing around, don't you?)"

Realising how close her face into me, I pushed back slightly, "Well, I was just thinking surely sometimes you are lost in your own thoughts…"

Lilith's smile grew wider as she leaned in closer to me, "So are thou finding thy way 'i thy lost? and wot the limitation of thou bid mana b? (So are you finding your way in your lost? And know the limitation of you called mana B?) " Her curiosity was reaching at climax.

I couldn't help but feel a bit flustered by her curious and intense gaze, but I managed to respond, "Unfortunately, I kept losing on my way, so I don't know the limitation of the mana B…" Her face quickly turned into sadness and disappointment, as if my answer was not what she had hoped for.

"I may get lost in my thoughts, but in that lost way, surely there is some way to a new thing which leads to the answer…"

"What doth thou mean? (What do you mean?)"

"Your rune, actually an indication of the limitation between two mana…"

"Thou mean…" At once, Lilith showed her black rune in front of her, "This?"

I looked closer at her rune, it was different from Aella's, the colour of Aella's rune was yellow with an inverted triangle and 12 cardinal directions, yet Lilith's rune was black and had no cardinal direction.

"May I ask you one thing? This rune, What is the purpose of this?"

Lilith looked at me and said, "The intent of this rune is to unlock the occulted potential within oneself (The purpose of this rune is to unlock the hidden potential within oneself.)"

"There you go, your answer about the limitation…"

Lilith's eyes sparkled with intrigue as she leaned in even closer, clearly intrigued by my response. "What do you mean by that?"

"Well as you can see, in fusion, there is a term of stability…" In nuclear fusion, it is more complicated if we are talking about the term stability, it means protons, neutrons, and photons, yet I don't quite understand all of that. However, let's make this magic fusion simpler and easier to understand, and most importantly bend it, "This state is where magic will be released as the creature wants... Rune is a medium for the fusion, it brings all the mana from the creature and the mana from the environment into one place…"

"Soft, yet 'i a small-scale spell, i do want not a rune and thou quoth there is a fusion 'i that spell, how doth i want a rune to apply certain spells? (Wait, but in a small-scale spell, I don't need a rune and you said there is a fusion in that spell, how do I need a rune to apply certain spells?)"

You know the answer well, not me, "It may be a small-scale spell, but it's so dependent on the environment, I explained before, that there is a certain limitation of mana B, as much the mana approaches this limitation, the spell may become more dangerous for the creature…"

"Why??"

"Because the creature's body isn't for the fusion…"

"What doth that mean?"

"In small-scale spells, the fused happens at the environment, so the environment takes the stability on that like a temporary vessel to fuse your mana into the environment. In simple terms, you give your mana to the environment since it can handle the fusion better than a living creature, and the environment burdens more of the spell than the creature…"

"What is divers than this rune?"

"In rune or your previous spell, you attracted the environment mana or mana B to you, however, your body or creature body can't fuse properly so it needs certain media to do fusion, and the rune comes into play. Your rune is a key to determine the limitation of mana B…"

"How doth we wot?"

"Are you dumb or what?"

"Hei!"

"Stability, that's the key. Stability in the fusion process is crucial to ensuring that mana B is properly utilised. Without stability, the mana B may be out of control, and your spell can be blown or become unstable. So if you want to know what the limitation is, you need to approach more spells without your rune, if the spell is not activated properly or gets blown out of control, it indicates it's not stable, and that's the limit."

Lilith was in silence. She turned her head down, absorbing the information. In a few seconds, she lifted her head with the biggest smile I had ever seen on her face, her head rushed into my face, and she exclaimed loudly, "Thou!!!"

"Yeah?!"

"Thou art marvellous for a short-living creature or human, doth thou understand what thou just explained? that was brilliant! (You're marvellous for a short-living creature or human, do you understand what you just explained? That was brilliant!)" Lilith exclaimed, her eyes shining with excitement. "E'en the elves who so thirsty for this thing canst not grasp it like thou didst (Even the elves who are so thirsty for this thing can't grasp it like you did.)"

Speaking of the elf, I need to know about the aksara… I moved back one step from her face, and said, "Speaking of elf, I want to know something from you…"

"One thing from me?"

"Yeah, an answer exactly. Why do you know about the aksara?"

Lilith's face was as confused as thermite like she didn't know what the hell I was asking, and I was right, "What doth thou mean by aksara this thing?"

"Your chanting, that's aksara…" Does she not know it? "Don't tell me you don't know it either?"

"I doth not quite understand what thou just asked, what is this aksara thing?"

"Aksara is a type of word that you used… ꦏꦸꦭꦲꦩꦤ꧀ꦱꦏꦫꦺꦴꦁꦱ꧉꧉꧉ that's aksara means we are safe from harm…"

Her eyes became sparkling again, and again she rushed into my face and asked, "Wherefore thou knowest the meaning of the chanting?"

Well, she doesn't know… "You were chanting it, not me…"

"Yet i chanted it, and i still do not understand the meaning behind it. I just memorised it because it hath been written and taught for generations. The chanting is received to hast protective faculties and is passed down through generations for that reason… (But I chanted it, and I still don't understand the meaning behind it. I just memorised it because it has been written and taught for generations. The chanting is believed to have protective powers and is passed down through generations for that reason…)"

I was confused because there were two types of chanting in the previous. The first was from Varania; she was just mumbling it, and I didn't see any similarity to the poem of Macapat. The second was from Lilith itself, there was some similarity from the poem of Macapat, the guru gatra and guru wilangan were similar with maskumambang 4 gatra and some wilangan and lagu with 12u, 8a, 8a, 8a. The original poem would be 12, 6, 8, 8 for the wilangan, and for the guru lagu, it would be 12i, 6a, 8i. 8a. So there was some modification on the chanting from the original poem. Why were there two different chantings?

I asked her, "Why there were two different chantings between you and Varania?"

"What thou you mean?" I asked her to me as she was confused.

"At first Varania's chanting was—" Wait a second, I realise it, I am just too focused on macapat that there is one type of poem that has similarity with Varania's chanting, it is Kakawin. It is older than macapat, so sometimes it is forgotten. All of these chantings are based on poems, and again the kakawin and the chanting from Varania have different styles, maybe it's a modification. What in the hell this world is?
